Schneider QOB140VH – Frequently Asked Questions

1) Will a QOB bolt-on breaker snap into a QO plug-on load center?
No. The QO Series 1-pole breakers in the QOB115VH, QOB120VH and QOB140VH numbers are bolt-on devices, so they fasten to the bus with a screw and need a panelboard whose interior is prepped for bolt-on QOB breakers. A plug-on QO load center bus has no bolt provision, so these will not seat in it. If your panel takes plug-on breakers, order the QO plug-on version in the same amperage instead.
2) Can I use this breaker to protect a rooftop AC unit or condenser circuit?
Yes, these QO 1-pole breakers are HACR rated, meaning they are rated for the motor loads found in heating, air conditioning and refrigeration equipment. That is the rating an inspector looks for on an HVAC branch circuit. Match the amperage to the equipment nameplate maximum overcurrent protection: 15 A, 20 A and 40 A are the amperages offered.
3) Is a 1-pole 120/240V QO breaker okay for a 240V two-wire circuit?
A single pole only lands on one bus leg, so it gives you a 120V circuit to neutral. The 120/240VAC rating describes the system it can be installed on, not two-wire 240V capability. For a straight 240V load such as a heater or compressor you need two poles, either a 2-pole QOB breaker or two of these with an approved handle tie.
4) Is this a standard thermal-magnetic breaker or does it include GFCI or arc-fault protection?
Standard overcurrent protection only. The QO 1-pole units in 15, 20 and 40 amp are catalogued as standard circuit breaker type with a standard function option, so there is no ground-fault or arc-fault sensing built in. Where the code requires GFCI or AFCI on a dwelling or specific commercial circuit, you need the dedicated QO GFI or CAFI device instead.
5) How much panel space does a 1-pole Schneider QO breaker take up?
One space. Each of these 1-pole QO breakers is 0.75 inch wide and occupies a single pole position, so a 42-space panelboard takes 42 of them. Depth behind the mounting surface is 2.91 inches, which matters if you are checking gutter clearance in a shallow enclosure.
6) Can I padlock one of these breakers off for lockout on a maintenance shutdown?
Yes. The listed accessory for these 1-pole QO breakers is the QO1HT handle padlock attachment, which holds the toggle in position for lockout/tagout. It is ordered separately, not supplied with the breaker.
7) Do these breakers meet RoHS and halogen-free requirements for a green building spec?
They do carry Schneider's Green Premium designation, are EU RoHS compliant and are built as a halogen-free product, with mercury and toxic heavy metals absent. Total lifecycle carbon footprint is published at 18 kg CO2 eq., and the environmental profile document reference is ENVPEP2111016 if your LEED or spec submittal needs it. Note the REACH declaration states the reference contains Substances of Very High Concern above the threshold.
8) If one of these QO breakers trips repeatedly, can it be repaired or does it get replaced?
Replace it. These 1-pole QO breakers are non-serviceable units with no field-repairable parts, and average life duration is published at 15 years. For MRO stock in a commercial building, keeping spare 15 A and 20 A bolt-on units on the shelf is the practical approach since those cover most lighting and receptacle branch circuits.
